Why is my shoulder popping?

If you have been told you are suffering from shoulder crepitus, there is no need to be alarmed. From the Latin word crepare, meaning rattle, crepitus is the medical term for a popping sound. It is a common condition where you hear a popping, cracking, or clicking sound in your shoulder joint. While it can worry you, shoulder popping without pain is often harmless. These sounds are generally caused by small gas bubbles in the synovial fluid within the joint, which burst due to changes in joint pressure. Understanding the shoulder joint, why popping occurs, and when to seek medical advice is essential for maintaining optimal shoulder health.

Why Is My Shoulder Popping Without Pain?

Joint sounds are often just that—sounds. Several factors can cause shoulder popping with no pain, and understanding these can help alleviate concerns.

• Cavitation: This is the most common cause. Cavitation occurs when small gas bubbles in the synovial fluid of the joint burst due to changes in joint pressure. It is similar to cracking your knuckles and is generally harmless.

• Ligament or tendon movement: Tendons or ligaments around the shoulder joint may shift slightly and then snap back, resulting in a popping or clicking sound that is typically painless. This is often due to normal joint movement and does not signify damage.

• Labral variations: The labrum is a piece of cartilage that surrounds the shoulder socket. Minor irregularities or variations in its shape can cause a clicking sound when the arm is moved but typically do not cause pain. These minor variations are usually harmless.

• Scapulothoracic bursitis: While bursitis usually causes pain, mild cases of scapulothoracic bursitis may only result in a popping sound as the shoulder blade moves over the rib cage. Bursitis involves inflammation of the bursa, but mild inflammation may not always be painful. 

When Should I See a Specialist About Shoulder Popping?

Persistent joint sounds should be evaluated by a specialist to rule out underlying conditions. Although shoulder popping without pain is generally not a cause for concern, there are instances where seeing a shoulder specialist is advisable:

• Persistent popping: Continuous popping could be a sign of a mechanical issue within the joint.

• Changes in mobility: If you notice a decrease in shoulder mobility or experience stiffness along with the popping sound, it is wise to consult a specialist.

• Onset of pain: If pain accompanies the popping sound at any point, it is crucial to seek medical advice to prevent further injury. Pain associated with joint sounds should not be ignored as it may signal an underlying problem.

How Do I Treat Shoulder Popping?

If your shoulder popping does require attention, several treatment options can help manage or alleviate the condition. Consulting with a specialist can provide tailored strategies to maintain shoulder health.

• Physical therapy: PT can greatly enhance shoulder function and minimize joint sounds. Therapists guide you through exercises designed to strengthen the muscles around the shoulder joint, improving stability and reducing the likelihood of popping.

• Lifestyle modifications: Adjustments in daily activities or exercise routines can help minimize stress on the shoulder joint, reducing the frequency of popping. Changing daily routines to lessen joint strain can help avoid unnecessary joint sounds.

• Manual therapy: Techniques such as joint mobilization or manipulation can be used to ensure proper alignment and movement of the shoulder joint. Manual therapy can align joint mechanics properly and decrease unusual sounds.

• Monitoring and observation: In most cases, shoulder popping without pain does not require intensive treatment. Regular monitoring and checkups with a specialist can ensure that the condition remains benign and does not progress. Keeping up with regular checkups is essential for joint health and avoiding complications.
